An object of this invention is to facilitate the operation of cutting away the sod as men- 7 tioned above.

Other objects are simplicity and inexpensiveness of construction.

Other objects and advantages will appear in the subjoined detailed description.

The accompanying drawing illustrates the invention:

Figure 1 is a broken view, mainly in vertical midsection, of a sod-cutting tool constructed in accordance with the provisions of this invention. 7

Figure 2 is a plan view, partly in section, from the line indicated by 2--2, Fig. 1. The cutters are omitted.

This produces two circular cuts, one immediately surround/1' ing the sprinkler head and one a short distance from said sprinkler head. The operator then rotates the tool by means of the handle 17 so as to cause the blade 11 to make a horizontal cut inthe sod to free the ring of sod from the earth. This horizontal cut may made of any desired depth according to the amountvofpressure brought to bear on the tool. The .cut may be made by rotating the tool once ;or the tool may be rotated a desired depth.

.After the sod has will be raised and placed over another sprinkler head and the foregoing described operations repeated. In event of the sod or dirt sticking within the cutter 8. it may be expelled as, for example, by the operator placing his footon the cross-head 22 and depressingit, thus causing the plunger 18 to descend to the cutting edge 10, thereby expelling any material that may not havereadily freed itself .from the cutter 8, and periphery of the cutter 7, when thetool was raised from the earth after cutting awa-ythe sod from around the sprinkler head.

Now describing the formof theinvention illustrated in Figs. 5 and 6. the elements that functionally correspond to those described above in connection with Figs. 1 to 4, are inbeen cutaway, the tool vided with a laterally extending tread member 25 on which the operators foot may be placed to force the cutter into the sod. The preferred form of the tool may also be forced into the sod by pressure of the operators foot when the foot is 'placedon the head 14.

I claim: 1 3

1. A sod-cutting tool comprising an inner member having a downwardly directed cutting edge all portions of which are equally spaced from a common vertical axis, an outer member attached to said inner member and having a downwardly directed cutting edge all-portions of which are equally spaced from said vertical axis a greater distance than said first edge, sod ejecting means'normally positioned between said members above said .edges, means for forcing said ejecting means downwardly toward said edges and a handle attached to saidinner and outer members for rotating said members about said vertical axis.

2. A sod-cutting tool comprising concentric hollow cylindrical cutting members, a blade between the cutting members secured to one of said cutting members and provided with a horizontal cutting edge,a head connecting the cutting members, a stem connected with the head and provided with a handle, an annular plunger between the cutting members, a cross-head shiftable along the stem, means connecting the cross-head with the plunger and passing through holes in the head, and a coil spring surrounding the stem between the head and the cross-head.

V dicat'ed by the same reference characters with the addition of the suifix a. In this instance,

1 there are two cutter blades 11a, said cutter i I blades being at different levels so that when 7 I as the tool is rotated, the lower blade willmake the cut at one level and the upper blade at a higher level. In this instance, the blades 110 are secured in any suitable manner to and pro ect laterally from the periphery of the cutter 7a. The cutters 11a are semi-circular,

the rear end of the upper one extending over the forward edge of the lower one so that any cut material discharging from the upper blade will discharge onto the lower blade.

The outer edges of the cutters 1111. are provided with downwardly projecting cutting edges 10a which are semi-circular so that they together make a circular cut when the tool is forced into the sod and turned. This modified form of the invention operates the same as described above for the preferred form. and, when the tool is' turned, thecutting edges 10a produce a circular out while the blades 11a make ahorizontal out.

The headl ta, in this instance, may be pro I
